Objective: The characteristics and differences of the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia were investigated to provide references and suggestions for the compilation of the Chinese Pharmacopoeia.
Methods: From the perspective of frame structure and main contents, the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia was compared.
Results: Each volume of the Chinese Pharmacopoeia had its general notice, including 34 to 48 items and 10 to 12 chapters based on different varieties collected in each volume. The Japanese Pharmacopoeia had 49 items not arranged by chapters. There are many differences on the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia, such as the definitions and expressions of names, determination of appearance, revision rules, risk assessment and quality control conception. The framework of the general notice in the Chinese Pharmacopoeia was clear, the content was specific and the operation was friendly. The term description of the general notice in the Japanese Pharmacopoeia was concise, and some terms need to be implemented under the guidance of professional knowledge.
Conclusion: In light of comparative study, every volume’s general notice of the Chinese Pharmacopoeia has its own characteristics. By integrating advanced analytical technique, combining the requirements with laws and regulations, and optimizing content and terms, all volume’s general notice could be explored to be coordinated and unified.

Objective To explore the effect and mechanism of esculin on hepatocyte steatosis by inhibiting protein kinase RNA-like endoplasmic reticulum kinase(PERK)/eukaryotic translation initiation factor 2A(eIF2A)/activating transcription factor 4(ATF4)signaling pathway.Methods Human normal liver cell line HL-7702 was used to induce a fatty degeneration model of hepatocytes in vitro with 0.5mmol/L free fatty acid(FFA)(oleic acid∶palmitic acid=2∶1)and treated with 50μmol/L,200μmol/L esculin for 24h.After the cell samples were broken by ultrasound,the supernatant was collected and the contents of alanine transaminase(ALT),aspartate transaminase(AST),malondialdehyde(MDA),glutathione(GSH)and triacylglycerol(TG)were detected.Using Nile red fat fluorescence staining to detect intracellular lipid droplets;Quantitative reverse transcriptase-mediated polymerase chain reaction(qRT-PCR)was used to detect the transcription levels of genes related to intracellular lipid metabolism processes.Western blot(WB)was used to detect the protein expression levels of pro apoptotic factors Caspase-3 and Bax,as well as PERK/eIF2A/ATF4 signaling pathway related proteins and phosphorylation levels in cells.Results The results confirmed that treatments of 50μmol/L and 200μmol/L of esculin significantly decreased the levels of FFA induced MDA,ALT and AST in hepatocytes(P＜0.05),and significantly increased the levels of intracellular GSH(P＜0.05).WB results showed that esculin treatment could significantly reduce the protein expression levels of Caspase-3 and Bax(P＜0.01).The results of Nile red staining and TG content detection confirmed that esculin treatment could significantly reduce the accumulation of intracellular lipid droplets and TG content(P＜0.05).The results of qRT-PCR showed that the expression levels of PPARγ,FASN,Srebf1,Dgat2,Mvk and Acaca in hepatocytes were significantly decreased after esculin treatment(P＜0.05).In terms of mechanism,the phosphorylation levels of PERK,eIF2A and ATF4 in hepatocytes were significantly reduced by esculin treatment(P＜0.05).Conclusion Esculin could improve lipid accumulation in hepatocytes by regulating the PERK/eIF2A/ATF4 signalling pathway,which plays a positive role in maintaining the healthy state of hepatocytes.

Objective:To investigate the clinical characteristics and vaccination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in maintenance hemodialysis (MHD) patients.Methods:It was a cross-sectional survey. Through wechat questionnaire star mode, the status of SARS-CoV-2 infection, clinical manifestation after infection and vaccination of MHD patients in Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine between December 8, 2022 and January 12, 2023 were retrospectively collected during the period that SARS-CoV-2 infection was managed with measures against class B infectious diseases. The patients were grouped according to whether they were infected with SARS-CoV-2 and whether they were complicated with pneumonia after infection during the study period. Logistic regression analysis was used to analyze the risk factors of SARS-CoV-2 infection combined with pneumonia or persistent symptoms after SARS-CoV-2 turning negative.Results:A total of 241 questionnaires were issued, and 223 valid questionnaires were returned, of which 175 patients (78.5%) were infected with SARS-CoV-2 during the study period. The time of negative conversion of antigen or nucleic acid after SARS-CoV-2 infection was 10 (7,14) days. Asymptomatic infections accounted for 10.3% (18/175). Symptomatic infections accounted for 89.7% (157/175), and the top five most frequent symptoms were cough (70.1%, 110/157), fever (64.3%, 101/157), pharyngeal pain (35.0%, 55/157), muscle pain (28.7%, 45/157), and nasal obstruction (21.0%, 33/157). Pneumonia was reported in 54.3% (95/175) of infected patients. There were no statistically significant differences in age, gender distribution, proportion of diabetes mellitus, and proportion of history of tumors between SARS-CoV-2-infected and uninfected patients (all P>0.05). Compared with the non-pneumonia group, the proportions of dyspnea (12.6% vs. 1.3%, χ2=8.181, P=0.004) and chest tightness (23.2% vs. 10.0%, χ2=5.293, P=0.021) in the pneumonia group were both higher. There were no significant differences in age, gender distribution, time of negative SARS-CoV-2 transition, number of symptoms and SARS-CoV-2 vaccination rate,and proportions of diabetes mellitus and tumors between the pneumonia group and the non-pneumonia group (all P>0.05). There were 48.6% (85/175) infected patients having long-lasting clinical symptoms after SARS-CoV-2 turning negative. Logistic regression analysis results showed that diarrhea was an independent influencing factor of pneumonia in MHD patients infected with SARS-CoV-2 [ OR (95% CI)=6.323 (1.061-37.682), P=0.043]. The number of symptoms at onset [ OR (95% CI)=1.571 (1.318-1.873), P<0.001] and history of tumors [ OR (95% CI)=0.206 (0.054-0.777), P=0.020] were independent influencing factors of long-lasting clinical symptoms. The SARS-CoV-2 vaccination rate was 7.2% (16/223) in MHD patients due to safety concerns (81.2%, 164/202). Conclusions:MHD patients are SARS-CoV-2-susceptible population. The clinical symptoms after infection are diverse, heterogeneous, and the proportion of complicated pneumonia is high. Diarrhea is an independent influencing factor of pneumonia in SARS-CoV-2-infected MHD patients. Nearly half of patients experience long-lasting clinical symptoms after SARS-CoV-2 turning negative. The low rate of vaccination in the MHD population necessitates increased awareness about the safety and efficacy of SARS-CoV-2 vaccine.

OBJECTIVE To explor e the effect of clinical pharmacists participatin g in fine management of pharmaceutical affairs among the inpatients in the department of gastroenterology based on diagnosis related groups （DRG）data. METHODS The discharged patients in the gastroenterology department of our hospital were selected as the research objects to compare the changes of DRG indicators and hospitalization related indicators before （from April to December 2019）and after （from April to December 2020 and from April to December 2021） pharmacists participating in fine management of pharmaceutical affairs in the gastroenterology department. The key DRG with the highest number of enrolled cases and DRG cases of the total cost overrun were analyzed to explore the deviation of various costs. The rationality of drug use was evaluated for the cases in each DRG that exceeded the benchmark hospital payment standard by three times ，with the help of prescription doctor ’s advice review. RESULTS In the first year of intervention ，the case combination index value of gastroenterology department was increased ，meanwhile，the cost consumption index ，time consumption index and average hospital stay were decreased significantly （P＜0.01）. In the second year of intervention ，total weight of the cases in gastroenterology department was increased ，while cost consumption index ，time consumption index ，hospitalization cost per time ，drug cost per time and average hospital stay were all decreased significantly ， compared with before intervention （P＜0.01）. Among the top five DRG ，the drug cost per time in the GZ 15，GZ13 and GJ 15 were all decreased significantly in the first year of intervention ；hospitalization cost per time and drug cost per time in the GZ 15，GZ13， GJ15 and GJ 13 were all decreased significantly in the second year of intervention （P＜0.01）；after the intervention of clinical pharmacists in DRG over-expenditure cases ，the over-expenditure rate decreased significantly （P＜0.001）. CONCLUSIONS The fine management of pharmaceutical affairs in our hospital has achieved certain results and promotes the rationality of clinical drug use，and provides a new entry point for the cost control and utilization of medical institutions under the background of 〔2020〕68号） DRG.

Objective:To determine the prevalence of sarcopenia and explore related influencing factors of sarcopenia in maintenance hemodialysis (MHD) patients.Methods:MHD patients aged ≥18 years old and receiving therapies of ≥3 months from March 2019 to December 2019 in Blood Purification Centre of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively enrolled in this study. General data of the patients were collected. Grip strength was measured by the Jamar dynamometer and the chair stand was measured by a chair of standard height to assess skeletal muscle strength and appendicular skeletal muscle mass was measured by dual energy X-ray absorptiometry. Baseline data between MHD patients with and without myasthenia were compared. Logistic regression analysis method was used to analyze the influencing factors for sarcopenia in MHD patients.Results:A total of 125 MHD patients were enrolled, with 68 males (54.4%), age of (59.4±14.9) years and median dialysis age of 51.0(23.5, 101.0) months. Sarcopenia was diagnosed in 39 cases (31.2%). Compared with MHD patients without sarcopenia, age, tumor necrosis factor-α, von Willebrand factor (vWF) and proportion of using α ketones were higher, and serum carbondioxide combining power (CO 2CP), prealbumin, albumin and proportion of regular exercise were lower in MHD patients with sarcopenia (all P<0.05). Multivariable logistic regression analysis results showed that low CO 2CP ( OR=0.717, 95% CI 0.576-0.892, P=0.003), high vWF ( OR=1.037, 95% CI 1.016-1.058, P<0.001) and no regular exercise ( OR=0.309, 95% CI 0.118-0.810, P=0.017) were independent influencing factors of sarcopenia in MHD patients. Conclusions:The prevalence of sarcopenia in MHD patients is high. Low CO 2CP, high vWF and no regular exercise are independent influencing factors for sarcopenia in MHD patients.

Objective To compare the trigger delay and work of trigger between neurally adjusted ventilatory assist (NAVA) and pressure support ventilation (PSV) in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with intrinsic positive end-expiratory pressure (PEEP) during mechanical ventilation. Methods AECOPD patients with intrinsic PEEP (PEEPi) greater than or equal to 3 cmH2O (1 cmH2O=0.098 kPa) were enrolled during invasive mechanical ventilation. Subjects were ventilated with low, medium and high pressure under either NAVA or PSV mode. Servo Tracker software continuously recorded the waveform of ventilator and respiratory mechanics indexes (including respiratory frequency, inspiratory tidal volume (Vti), minute ventilation volume (VE), peak airway pressure (PIP), inspiratory time), and calculated trigger and expiratory conversion delay time, work of trigger and total work of breath. Results A total of 14 AECOPD patients were enrolled with the average PEEPi (4.3±1.3) cmH2O. PSV inspiratory trigger delay time was positively correlated with PEEPi (r=0.913, P<0.05). Compared with PSV, NAVA significantly decreased trigger delay time in low, medium and high pressure level groups [(48±17) ms vs. (167±86) ms, (63±65) ms vs. (247±240) ms, (63±49) ms vs. (342±192) ms,respectively all P<0.05]. Similar results were shown as to work of trigger [(0.92±0.36) μV?s vs. (1.22±0.70) μV?s, (1.08±0.51) μV?s vs. (1.62 ± 1.25) μV?s, (1.20 ± 0.96) μV?s vs. (2.29 ± 1.02) μV?s, all P<0.05]. Trigger delay time increased according to the increase of pressure level in PSV mode.Conclusion The presence of PEEPi in AECOPD patients leads to obvious trigger delay under PSV mode, which is positively correlated with PEEPi level. NAVA significantly reduces trigger delay time and work of trigger compared with PSV mode.

ObjectiveTo discuss the effects of targeted nursing intervention on pregnancy outcome and neonatal weight in patients with gestational diabetes mellitus (GDM). MethodsTotally 108 GDM patients treated in our hospital from July 2017 to February 2019 were selected and divided into intervention (n=54) and control (n=54) groups according to the random number table. Patients in the control group received conventional nursing care, while patients in the intervention group received targeted care on this basis. Patient＇s blood glucose level, pregnancy outcome, neonatal weight and satisfaction with nursing before and after nursing care were compared between the two groups. ResultsThere was no statistically significant difference in blood glucose levels between the two groups before nursing intervention (P＞0.05). Fasting blood glucose, 2 h postprandial blood glucose and glycosylated hemoglobin levels were lower after nursing intervention in both groups. The levels of the intervention group were even lower than those of the control group, and there were statistically significant differences between the two groups (P＜ 0.05). The incidence of malignant pregnancy outcome and neonatal complications of the intervention group were lower than those of the control group after nursing intervention, and patient＇s satisfaction with nursing was higher in the intervention group than in the control group, and there were statistically significant differences between the two groups (P＜ 0.05). ConclusionsTargeted nursing intervention can effectively reduce blood glucose levels of GDM patients and the incidence rate of adverse maternal and neonatal outcome, and improve patient＇s satisfaction, which is worth promoting in clinical practice.

Objective To evaluate the value of microcirculation and oxygen metabolism evaluation (MicrOME)in acute kidney injury(AKI) evaluation in patients with septic shock after resuscitation. Methods Consecutive patients with septic shock after resuscitation and mechanical ventilation were enrolled from October 2016 to February 2017 in ICU at Peking Union Medical College Hospital.Patients were divided into 3 groups based on 10 min transcutaneous oxygen challenge test transcutaneous partial pressure of oxygen(PtcO2)and venoarterial pressure of carbon dioxide difference(Pv-aCO2)/arteriovenous O2 content difference(Ca-vO2)by blood gas analysis, i.e. group A [ΔPtcO2>66 mmHg(1 mmHg=0.133 kPa) and Pv-aCO2/Ca-vO2≤1.23], group B (ΔPtcO2≤66 mmHg), group C (ΔPtcO2>66 mmHg and Pv-aCO2/Ca-vO2>1.23). Heart rate,mean arterial pressure,central venous pressure,noradrenaline dose,lactate,Pv-aCO2,Ca-vO2, lactate clearance, central venous oxygen saturation(ScvO2) and liquid equilibrium were assessed after resuscitation.AKI staging based on Kidney Disease Global Improving Outcomes (KDIGO) clinical practice guideline was analyzed. The predictive value of lactate,ScvO2,Pv-aCO2/Ca-vO2 to progression of AKI after resuscitation was determined using receiver operating characteristic(ROC)curve analysis.Results A total of 49 septic shock patients were enrolled including 30 males and 19 females with mean age of (61.10±17.10) years old.There were 19 patients in group A,21 patients in group B, and 9 patients in group C. Acute physiology and chronic health evaluation Ⅱ score was 20.92±7.19 and sequential organ failure assessment score 12.02±3.28. There were 4 patients with AKI and 1 progressed in group A,11 patients with AKI and 2 progressed in group B, 6 patients with AKI and 4 progressed in group C. The cutoff value of Pv-aCO2/Ca-vO2 was equal or more than 2.20 for predicting progression of AKI,resulting in a sensitivity of 85.7％ and a specificity of 73.8％.Conclusion MicrOME is a significant parameter to predict the progression of AKI in patients with septic shock after resuscitation. Pv-aCO2/Ca-vO2 is also a good predictive factor.

Objective To evaluate the prognostic value of arterial blood lactate clearance based on central venous oxygen saturation and perfusion index in patients with septic shock related myocardial injury after early goal-directed therapy.Methods One hundred and fifty-seven patients with septic shock after early resuscitation were enrolled from August 2013 to July 2016 in ICU at Peking Union Medical College Hospital.Parameters indicating early resuscitation included central venous pressure (CVP) 8-12 mmHg (1 mmHg=0.133 kPa),mean arterial pressure (MAP)＞65 mmHg,central venous oxygen saturation(ScvO2)＞70％ and urine volume (UO) ＞0.Sml · kg-1 · h-1 and arterial blood lactatc (Lac) ＞2 mmoL/L.Patients were divided into group A [ScvO2＞80％ and perfusion index (PI)＞1.4],group B(ScvO2＞80％ and PI＜1.4),group C (ScvO2＜80％ and PI＞1.4),group D(ScvO2＜80％ and Pl＜l.4).Hemodynamic parameters and tissue perfusion indexes at 2 hours(T2),4 hours(T4) and 6 hours(T6) after early resuscitation and troponin Ⅰ which indicated myocardial damage,on day 1 2 3 in ICU were recorded.Results (1)Lac clearance in group C was the quickest,which was 34.57％ (21.44％,44.20％),58.33％ (30.19％,70.79％),71.43％ (53.75％,82.79％) at T2,T4,T6 respectively.(2)The maximal incidence of myocardial damage was in group B(85.0％) and the lowest in group A (45.7％) on day 1 in ICU.Whereas on day 2,group C showed the lowest incidence of myocardial damage (29.3％) and group B the highest(70.0％).On day 3,the proportion of elevated troponin Ⅰ in group B was 70.0％,which was significantly higher than that of group B (29.3％,P＜0.008).(3)Logistic regression analysis suggested that the rate of Lac clearance at T4 in group B was related to the incidence of myocardial damage on day 2 and 3 in ICU.Conclusions The combination of PI and ScvO2 as a resuscitation target in patients with septic shock facilitates Lac clearance as the goal of resuscitation.The rate of arterial Lac clearance based on ScvO2 and PI is correlated with myocardial injury in patients with septic shock after early goal-directed therapy.

Objective To explore airway remodeling and air trapping in asthmatic patients with low dose CT scanning and quantitative analysis. Methods 52 stable asthmatic patients in which 29 were severe and 23 were slight,and 20 healthy control cases were underwent low dose dual phase CT scanning. The LA/BSA, WA/BSA, TA/BSA, WA%and Pi10WA were analyzed as airway remolding indexes. The MLD of expiratory, VI-850 (%) of expiratory, MLD E/I, VI-850E-I (%) and VI-850/-950E-I (%) were analyzed as air-trapping indexes. One-Way ANOVA or H Kruskal-Wallis was used to analyze the above indicators. Results Airway remodeling indexes and LA/BSA were (9.6 ± 2.6), (11.0 ± 3.4) and (12.6 ± 3.0)mm2/m2 in severe asthmatics group, non-severe asthmatics group and healthy control group respectively, and there was significant difference between the three groups (F=5.60, P=0.006). WA%of each group was (65.1 ± 2.5)%, (63.3 ± 4.4)%and (62.0 ± 3.0)%, and there was significant difference between the three groups (F=5.53,P=0.006). The Pi10WA was (18.4±2.6), (17.7±3.1) and (16.4±1.4) mm2 respectively with significant difference between the three groups (F=3.59 ,P=0.033). Air-trapping indexes, MLD of expiratory of each group was-(771 ± 59),-(724 ± 43) and-(676 ± 60) HU respectively with significant difference (F=5.60, P=0.006). VI-850(%) of expiratory of each group was 30.79(30.45)%, 13.53(12.09)%and 2.85(6.87)%respectively with significant difference (H=17.20,P<0.001). Conclusions Low dose of CT scan and quantitative analysis can provide an objective and quantitative information for patients with airway disease of asthma, and both WA% and Pi10WA were objective indexes. The severe asthmatic patients were associated with obvious airway remodeling and air trapping compared with non-severe asthmatic patients.
